Would you like to stay healthy until you're 100? For most of us, the answer is, of course, yes. But why do some people live longer, and is it achievable?
In this episode, best-selling author and longevity expert Dan Buettner, explores what decades of studying the people who live the longest reveal about health and lifespan.
Instead of chasing hacks, the science suggests that a longer life is shaped by everyday food, social habits, and the places people live. We’ll look at practical habits seen across the world’s blue zones, rare global hotspots where celebrating your 100th birthday is common. Rather than relying on willpower, Dan explains why changing your routine and environment may be easier and more effective. By the end of the episode, you’ll have some simple tips to help you start your day like you live in a Blue Zone - and increase your chances of living healthily to 100.
